Regarding the whole felon-waiting-for-a-prosecutor thing, she says that "The Guidance will not be applied to possession, ownership or transfer of an Assault weapon obtained prior to July 20, 2016." Despite separately saying that all of the guns sold since 94 were "illegal," she's very clearly saying - in her official guidance - that it doesn't apply to rifles obtained before yesterday. In the absence of her changing her mind, this new interpretation doesn't impact the possession, ownership or transfer of an Assault weapon that had been obtained prior to July 20, which makes sense because she'd be facing a new set of legal challenges if she was trying to impose this specious decree retroactively.
In a world where her whims are law, rifles that fit her definition of assault rifles and that were "obtained" between '94 and yesterday are fine for us to own.
